STEAM WATER-HEATER.

Application filed December 17, 1913.

To all whom it may concern Be it known that I, EVERETT C. CIRCLE, a citizen of the United States, residing at Coalton, in the county of Okmulgee, State of Oklahoma, have invented certain new and useful Improvements in Steam Water-Heat ers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in water heaters and particularly to steam water heaters.

The principal object of the invention is to provide a simply and novelly constructed device for heating a continuous stream of water by injecting steam thereinto.

Another object is to provide a device of this character in which the steam and water will be thoroughly and intimately mixed to produce hot water.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is an elevation of my steam water heater. Fig. 2 is a vertical longitudinal sectional view therethrough, partly broken away. Fig. 3 is a horizontal sectional view on the line 33 of Fig. 2 looking upwardly. Fig. is a vertical longitudinal sectional view taken on the line 4-4 Fig. 2 and looking to the right. Fig. 5 is a vertical section of the lower portion of the casing showing a modification thereof. Fig. 6 is a section on line 66 of Fig. 5 taken in the direction of the arrow, the cylindrical portion of the casing being omitted.

Referring particularly to the accompanying drawing, 10 represents an elongated casing having a. globular lower end 11. The upper end of the casing is interiorly threaded and receives therethrough a steam nozzle 12. In one side of the upper portion of the easing is a nipple 13 to which is connected a cold water conduit 14, and in one side of the globular portion below the nipple 13 is another nipple 15 to which is connected a conduit 16 for conveying the heated water to the point of use. It will be noted that the Specification of Letters Patent.

lower or inner end of the nozzle 12 is disposed below the lower side of the nipple 13, this end being contracted so as to form a small outlet opening 17.

In the use of the device, the nozzle being connected to a source of steam supply, water is permitted to flow into the casing from the pipe 14 and out through the pipe 16. \Vhen the proper flow of water is obtained, the steam is turned on and caused to discharge into the water and cause the same to be whirled in the globular end of the casing. The steam thus thoroughly mixes with the water and effectively heats the same before it passes through the pipe 16.

In the pipe 14 is a controlling valve 18 for regulating the flow of the cold water, while in the pipe 16 and the pipe 19 which is connected to the nozzle are respectively arranged the valves 20 and 21. These valves control the outflow of heated water and the inflow of steam. It will thus be seen that by regulating the flow of the cold water, as well as the steam any degree of temperature can be obtained from the natural low temperature of the water to the high temperature of the steam.

This device is particularly adapted for shower baths, and by attaching a spray nozzle 22 to the outer end of the pipe 16 a fine spray of water of the proper temperature can be obtained. When the device is used particularly and solely for shower bath pur' poses the nipple 15 is omitted and this side of the end of the casing closed. The lower end of the casing is then provided with a plurality of openings 23 for forming the spray and a baflle wall 24 arranged below the nozzle 12 to prevent the direct discharge of steam from the spray and to cause it to thoroughly mix with the water.

From the foregoing it will be seen that I have provided a simple and eflicient device of this character, and one which can be quickly and easily connected with the Water system adjacent a steam plant.

lVhat is claimed, is

A steam water heater comprising a mixing chamber including a hollow spherical portion, a pipe of lesser diameter leading therefrom, a steam pipe engaged in the otherwise free end of said pipe and having its end at a point out of alinernent with the first therein reduced and terminating intermementioned pipe. 1.
